Rolex Datejust Yellow Rolesor — Black Index Dial, 46-Diamond Bezel | Ref. 178383

Among the most striking colour contrasts in the Datejust 31 lineup, this Yellow Rolesor reference 178383 pairs a deep black dial with applied index hour markers against the warm lustre of 18ct yellow gold and Oystersteel. The black dial — commanding and sophisticated — creates a dramatic foil to the 46-diamond bezel that surrounds it, with each brilliant-cut stone set in yellow gold to deliver a continuous band of light. The Yellow Rolesor construction of the case and Jubilee bracelet reinforces the warm metallic harmony across the piece.

Internally, the Calibre 2235 self-winding movement provides the power, offering ±2 seconds per day precision and a 48-hour power reserve. Like all Datejust references of this generation, the 178383 carries Superlative Chronometer certification, Rolex's own mark of accuracy verified post-casing. The Oyster case is water-resistant to 100 metres, sealed by the Twinlock winding crown and secured by a solid caseback.

The black-dial variant of the 178383 is consistently one of the more in-demand configurations of the Datejust 31 in the secondary market, with the high-contrast combination of noir dial and blazing diamond bezel appealing equally to collectors of jewellery-set Rolexes and those drawn to the bold architectural contrast. The yellow gold Rolesor construction keeps the piece within the Rolex two-tone tradition that dates back to the 1940s, while the diamond bezel and black dial give it a thoroughly contemporary energy. A compelling choice for the discerning collector.
